GAS HEATER.

Application filed June 28,1919. Serial No. 307,454.

To fr?! fio/:om t may concern.'

Be it known 'that l, lomos F. ADMIS,

citizen ot the United States, residing` at Pittsburgh, in the County of Allegheny and State of Pennsylvania, have invented certain new and useful lniprovenients in Gas Heaters oiI which the followingl is a specification.

This invention relates to gas-heaters, and belongs particularly with that class or .type

wherein openworlr i''ornis of lire-Clay are ar-` nia-y be advantageously land cheaply 1nanu-.

laetured, and which result it is believed in unusual economy in tune when assembling the parts duringl manufacture, and in thev use ol' for heating the radiante 'and maintaiingg` thein in the desired heated' state.

In the accompanying drawings the special construction and disposition of the parts ot this invention are set forth, and Fig. l represents a side view of the burner, with aportion broken away to disclose the flow d vider located within. Fig'. 2 isa top plan view of the radiant-support-ing plate or base. F 3 is a crosssection of the radiant-supporting pla-te on the broken line 3-3 of Fig. 2. Fig'. l is a' cross-section of the plate on broken line lr-il of Fig. 2. Fig'. 5 is a crossseotion of the `plate on the broken-line ot' Fig. 2. Fig. (i is a. ,longitudinalsection of the radiant-supporting plate on the broken line 6 6 cil Fig. 2, and shows also the nozzle plate and nozzles rin position with respect to the radiant-supporting plate. Fig. 7 is e. plan View ot one end of theradiant-supwort-plate iull size, showing' the. radiants ind tir-ebook in place and in horizontal secio i on line --TY of 8. Fig. 8 is a. vertross-section o.. the parts assembled. a front view of the clay lirebaelt bail tor retainingiv the radiante. .it the description and drawings ter used to refer to the saine wing the rFhrough "i the salue letpart.

Considering' the drawings. particularly l? ea lthe stove casing A has the usual open t int @fand near the bottoni the casing is horizontally partitioned interiorly by the plate B that is secured to the casing by lugs bolts such as the connection ils best shown in F l the burned C has the intake tube D tor gas and air, and it will be observed that the hollow body of the burner is largest at about the middle and decreases in size gradually towards the ends. ln the lai-gest part of the hollow interior of the burner C is located the iioiw divider el, usually formed integrally with the walls of the body of the burner and extending towards the int-alie tube D. rllhe body of the burner is open at the top and has a flange E extending about it. By ineens of screws e `there is secured to the flange E and closing the top ol' the burner, a nozzle plate F having' nozzles in a straight row. lt is also illustrated in Fig. l that the flow divider (Z is situated below the nozzle plate l? and there is a space between the liow divider and the nozzle plate `lj'or the gas and air to pass freely. The flow divider splits ythe strc-ain or How ot and air passing in by way .olL the intake tube D? causing` the divisions of the fliow tonieve towards the dilierent ends oit' the burner.

ers shown in Figs. l, 2, 6, and S, certain oi the nozzles f the ends oi the row oi nozzles7 have vertical `uns or extensions such those niarhed Gi G1 and C2, and each of those extensions has a shoulder such as the shoulder g shown in'Fig. 6, and it will be noted that the shoulder g engages one of the openings H, ol which the plate B has a row co,rresponding,` in positions to the positions ot the nozzles f. 'lhe purpose oi the construction and the functions oi: the tins are three-told. ller one purpose, it is desired that the burner (l shall be ifreely removable,

and the shoulders g engage the openings in the plate B without wedging or binding, and the burner may be easily taken away from the plato. For a second purpose, it may be explained that certain ot the shoulders y. as best illustrated in Fig. 7, are placed on the sides ol the nozzles which lie towards the ends ol the i'iozzle plate ll. lfh re is but one shoulder on eacli oit the nozzles provicmd with the it is believed. to be clear that suoli arri igenient of 'the shoulders as mentioned above prevents displz'lcenient ol the nozzle plate and7 oonsefluently `the burner C lengthwise when .in position and engaging' the plate B. third purpose it .may be stated that the vsnoulders on the extensions such as Gf and G2 are placed on the sides of the nozzles l-Owapgis elle sides or the :nozzle plate, and that such shoulders are located on one sideof one nozzle and on the opposite side of the other nozzle. Thus the burner while freely removable is, when in position, securely heldagainst displacement lengthwise or sidewise. lfor the purposes of this descriptionk the plate B is termed the radiant-supporting plate, and it has erected.` upon it, and

usually formed integrally with it, the rectangular barrier or guard it within which the row of'openingslll is located.

The barrier is to limit the displacement of the `i-adiants forward or backward.

ln fact the 4barrier 'or guard prevents theA displacement of the lower ends `of the radiants in'any direction horizontally. Confl sidering Figs. 3, l, and 'Lit will be observed that the guard 7L is highest at the' rear, and near the ends ofthe nozzle plate B the guard extends forwardly while'lessening in height. Therefore, the feet of the radiants at the ends of therow of radiants cannot be displaced backwards or to the right or left, while each may befreely lifted out vertically. lt will be further noted lin Fig. 7, that the guard extends like a lowvfence in front yof the feet of the radiants, ywhich are individually `separated by wall is encountered.y The barrier `has a 'front wall and a rear wall, the latter being f relatively highest. The front wall is made less rin height for convenience in placing the radiants in position. rlhe displacement of the -radiants sidewise is prevented by the l/shaped extensions J ofthe front wall of the barrier which project between the openings lil. ln Fig. 7 it willv be noted that the radiants '7' are positioned by the 'barrier walls and the V-shapedfmembers J directly over thev openings H and burner nozzles f and v that they cannot move to' become displaced in either direction, excepting vertically when it is desiredto remove them.

At the back of the radiants is the usual iireback l of refractory niate'riahin the side walls of which is pivoted a bail k, which Awhen the radiants are in place lies over vthem in front as set out in 1Eig. 8.

The tops of the radiante are thus prevented from falling forward, yet the bail-is easily raised when it is ldesired to remove or tol replace the radiante. l

Considering l? 7, it will he noted that the fins, or extensions Gr, G', G2, project from the nozzles j at the end of the row of nozzles, iii different directions. That is to say, the fin" or extension G extends towards the front wall of the barrier while 'the fin e Gf extends to the right and thevJlvGZ prou jects towards the rear'walll of thebarrier.v

lt has been explained that each extension or iin has a shoulder such, as the shoulder g, engaging the opening l-l of the plate B, and it is believed to be clear that the nozzles cannot be displaced forwardly because of the engagen'ient of the shoulder ofthe extension G andE the opening of the plate B. Sigmilarly, the end of the row of nozzles cannot be rdisplaced rearwardly or towards the right hand side by reason ofthe engagement of `the shoulders of the extensions G2 and G. ln Figs. l and 2 it willr be seen that there are like extensions provided for the nozzles at the other end of the row of nozzles, and displacement forward or backward or towards the left hand side is prevented by. the shoulders of those r extensions. lt will be thel nozzles from passing upwardly more than a certain distance through the openings l-l inplate B, and that the tops of the noz noted in Fig. v6 that the shoulders prevent drawings. 'When the burner is in place, the .llame passes upwardly inside the radiants and causes them as well as the freback to glow with intense heat and fromk which there' is an immense amount of radiation.

When cool, the radiants are easily removed `by lifting the bail 70, and there isl no positive attachment whatsoever of the nozzles and iooV the plate B, either being readily separated trated gives a large mixing chamber for the y gas and air and an unusual saving of gas is `found to result in practice.

Having now explained this invention and themode of its operation, what I'claim isflln a gas heater, the combination with a heater casing, of a partition plate secured horizontally within the lower portion of the vcasinfriand havino a series of o enino's arb D 2D ranged in line lengthwise of the plate, a

burner located below the plate and having a row of nozzles arranged in the said open- Y 'ings inthe plate, and means for positioning the burner as vthe partsare assembledv com Np'rising a part'of the number of nozzles'near theends of the rowV of nozzlesprovided with vertical fins, the said iins being located .intrus r. anar/rs.

ln testimony whereof I aiiix my signature.
